Once upon a time this band was called Reading Rainbow. The Cosby-sweater deadpan of the name, plus the fact that the first album was called Mystical Participation, was pretty much all you needed to know about its brand of amiably dull noise-pop — until recently, anyway. This year, with the addition of some personnel, a name change that apparently appeased both LeVar Burton and Carrie Brownstein, and a new album out in January, Bleeding Rainbow is newly serrated and maybe, just maybe, good enough to be Philadelphia's great bleary hope. The new record, Yeah, Right, is a swirly, grimy, improbably buoyant litany of guitar-soaked, female-fronted slacker rock; you wouldn't think songs that exude such listlessness could get stuck in your head so efficiently, but there it is. Never hurts to brush up on the fundamentals.
